ADOLF CONVERT, OF NEIV YORK, N. Y., ASSIGNOR TO THE AMERICAN CARBONATE COMPANY, OF SAME PLACE.

FLUID-PRESSURE REGULATOR.

SPECIFICATION forming part of Letters Patent No. 366,995, dated July 19, 1887.

Application filed April 14, 1887.

To all whom it may concern.-

Be it known that I, ADOLF CONVERT, asubject of the Emperor of Germany, residing at New York, in the county and State of New York, have invented new and useful Improve ments in Fluid-Pressure Regulators, of which the following is a specification.

In the use of fluids-such as liquid carbonicacid gas-under pressure in a reservoir it is usual to place a pressure-regulator or reducing-valve between the reservoir and the point where it is desired to use the fluid for the pur pose of automatically regulating the pressure of the fluid in its passage to the point where it is to be used.

The object of my invention is to provide a novel fluidpressure regulator or reducingvalve; and to such end it consists in the novel construction and combination ofdevices hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure 1 represents a vertical section in the plane a: m, Fig. 2. Fig. 2 is a similar section in the plane y y, Fig. 1, and looking in the direction of the arrow opposite to that plane. Fig. 3 is a detached side view of the valve and valveseat on a larger scale than the previous figures.

Similar letters indicate correspondingparts.

In the drawings, the letter A designates a chamber, in which is secured the diaphragm B, and which communicates through a channel, a, with a fountain containing-a liquid un der pressuresuch as liquid carbonic-acid gas. The channel a is formed in a plug, a, which is securely connected to the fountainas, for example, by a nut, K, engaging a screw-nozzle, I, on the fountain. A packing, U, secures a tight joint between the nozzle I and the nut K. A filter, L, in the channel a prevents impurities from passing through said channel.

To the chamber A is screwed a thimble, M. The plug a is provided with a screw-thread engaging a corresponding screw-thread on the thimble M. A packing, P, between the thinlble M and the chamber A secures a tightjoint between said thimble and chamber. A jamnut, N, screwed onto the screw-thread of the plug a, so as to jam against the thimble M, prevents accidental motion or dislocation of Serial No. 234,780. (No model.)

the plug a. A packing, 0, between the nut N, thimble M, and plug a, prevents liquid from escaping from the chamber A along the screwthread of the plug a. The thimble M is further provided with a screw-thread for receiving the screw-thread V on the stem G of the valve H. The inner end of the plug (1 forms a seat for the valve H, formed by the end of the stem G. Said valve is by preference made of india-rubber, so as to secure tight closing against its seat. The thimble M may be considered a valve-chamber for the valve H. The revolution of the stem G will cause the valve H to be moved to or from its seat. As the screw-thread on the plug a enables said plug to be set more or less into the thimble M, the plug a can be adjusted in proper relative po sition to the valve H, so as to be in position to have its channel a securely closed by said valve when required.

The diaphragm B is connected to the valve stem G by a lever, F, link E, and bracket D, and said lever, link, and bracket are suitably pivoted or jointed. The diaphragm Bis made of suitable materialsuch as leather or indiarubberand may be strengthened or re-enforced by a suitable devicesuch as an elastic metallic disk or plate-(), which has a tendency to retain the diaphragm B in its normal position, which is indicated in dotted lines in Fig. 1. \Vlien in its normal position, the diaphragm B, by means of bracket D, link E, and lever F, holds the valve H in its open position.

The resisting power or rigidity of the diaphragm B can be regulated by an adjustingscrew, \V, and a spring, X. By turning the scr ew \V in one direction or another the tension ofthe spring Xis increased or diminished, so that greater or less pressure is required to depress the diaphragm B. The spring X has a tendency to retain the diaphragm in its normal position. The edges of the diaphragm B are suitably secured, as, for example, be tween the flanges of two sections of the chamher A, which are held together by suitable devicessuch as screws 0.

The chamberA is provided with an escapenozzle, Q, to which is secured a stop-cock, T, having an escape opening or tube, S. A packing, R, between the nozzle Q and the stopcock secures a tight joint.

The bracket D is secured to the diaphragm B-by a screw-shank, Z, and aunt, b. Aplate, Y, sits against the diaphragm B, and the nut I) sits against the plate Y. A nut, 0, provided with a packing, d, is screwed onto the plate No gas can Y, so as to surround the nut I). thus escape from the chamber A along the shank Z. i

As already stated, when the diaphragm B is in its normal position, which is indicated by dotted lines in Fig. 1, the valve 11 is open or away from its seat. A fluid-such as carbonicacid gas-under pressure canthus pass through the channel a into the chamber A. As the fluid under pressure collects in the chamber A the diaphragm B is actuated or bulged, so as to impart motion through the bracket D, link E,-and lever F to the stem G in such a direction that the screw-thread V carries the valve H against its seat, so as to close the channel a and prevent any more fluid from entering the chamber A through the channel a. On opening the stop cock T, part of the fluid in the chamber Acan escape, thus reducing the pressure in said chamber and allowing the diaphragm B to move back toward its normal position, whereby the valve H is moved away from the mouth of the channel a to open said channel. Fluid under pressure-can then again enter intothe chamber A through the channel (1. until the fluid under pressure has again collected in the chamber A to such an extent that the diaphragm B is bulged sufficiently to again cause the valve H to close the channel a. The pressure in the chamber A is thus prevented from exceeding a certain degree. ,7

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the chamber A, of the diaphragm B, secured in said chamber, the thimble or valve-chamber M, the plug a,

having a channel, a, and extending into the valve-chamber M, the screw-stem G, fitted into a screw-socket in the inner end of the valvechamber, the valve H, formed by one endof 5 the screw-stem, the lever F, secured on the other end of the screwstem, and connections between the lever]? and thediaphragm B, substantially as set forth.

2. The combination, with a screw-stem, G, v

and a suitable socket or chamber for saidstem, of a diaphragm, B, for operating said stemeonnections between said diaphragm and stem, a nut, b, for securing the connections to the diaphragm, and a packing-nut surrounding the nut b, substantially as set forth.

3. The combination, with a screwsten1, G, provided with a valve, H, and a suitable socket or chamber for said stem, of adiaphragm, B, for operating said stemconncctions between the diaphragm and the stem, a nut, b, for securing the connections to the diaphragm, a plate, Y, engaged by said nut 11, and a packing-nut secured to the plate Y and surrounding the nut'b, substantially as set forth.

4. The combination, with a chamber, A,

having a thimble, M, providedwith an internal screw-thread, of a plug, at, having a channel, a, and provided with a screw-thread made to engage the internal screw -thread of the thimble M, and ajam-nut, N, made to engage the screw-threadof the plug a and to bear against the thimble M, substantially as set forth.

In testimony whereof I have hereunto set my hand and seal in the presence of two sub scribing witnesses.
